The shape of the water retaining sheet 2411 may be as shown in FIG. 15, and the height of the water retaining sheet 2411 is lower than that of the outer wall 2412 of the water channel 241, and is designed to be serrated to achieve the effect of slowing water flow.

In some illustrative embodiments, a water filter 206 is further provided within the water tank 202. The upper water pipe 251 extends into the water tank 202 and is connected to the water filter 206. The water filter 206 functions to purify the water so that the water entering the water channel 241 is purified by the water filter 206 to remove undesirable substances such as impurities and bacteria in the water.

In some illustrative embodiments, a connecting seat 208 for fixing the lower water pipe 252 of the water pump 205 is provided within the water channel 241, so that the lower water pipe 252 does not move due to water flow during pumping of water.

In some illustrative embodiments, the water pump 205 and the water channel 241 are placed inside a housing of the humidifying device. The water tank 202 is separate from the housing of the humidifying device, and the humidifying housing is provided with a groove for having the water tank placed therein. The housing of the humidifying device comprises a humidifying top cover 201, a front humidifying housing 204, and a rear humidifying housing 203. The water pump 205 and the water channel 241 are both disposed within front humidifying housing 204. The rear humidifying housing 203 is connected together with the front humidifying housing 204 via connecting members such as bolts or slots. The humidifying top cover 201 is fastened to the upper surfaces of the above two housings and is fixedly connected together therewith to form the housing of the humidifying device. The rear humidifying housing 203 is provided with a groove the structure of which matches with the water tank 202, so that the water tank 202 can be freely detached from the housing of the humidifying device for the convenience of the user.

Optionally, a slide rail 231 may be provided at the bottom of the groove and a slideway may be provided in the corresponding position on the bottom of the water tank 202 to facilitate the removal of the water tank 202 more quickly and effortlessly.

In some illustrative embodiments, the humidifying device comprises an air duct penetrating through the humidifying device. The water channel 241 surrounds the air duct.

The specific arrangement may be as follows: after the front humidifying housing 204 mates with the rear humidifying housing 203, there is an air inlet 209 dedicated for ventilation at the bottom of the humidifying device. The water channel 241 has a hollow design that surrounds the air duct and increases the rate of water evaporation around the air duct (i.e., the water channel 241) when the air passes through the water channel 241. An air outlet 211 for ventilation (from which water vapour is evaporated outwardly) is provided on the upper surface of the humidifying device (i.e., the humidifying top cover 201).

Further, the air duct runs through the centre of the humidifying device. The air duct runs through the centre of the humidifying device and is also located in the centre of the water channel 241.

Since the air duct needs to pass through the whole humidifying device, the whole humidifying device can be regarded as a ring-like structure (in cross section), the shapes of the inner and outer rings may be the same or different, and the inner or outer ring may be of a round, square or triangular structure. The humidifying device is preferably concentrically ring-shaped, and this design is more conducive to ventilation and evaporation of the water vapour.

Optionally, the shape of the inner ring defines the structure of the air duct, and the longitudinal section of the air duct may be rectangular or be of other structures such as a trapezoid; for a better understanding, if the longitudinal section of the air duct is rectangular, it is approximately understood that the air duct is of a cylinder or cubic structure, and if the longitudinal section is a trapezoidal, the air duct may be of a nearly circular cone structure.

In some illustrative embodiments, the humidifying device comprises a power-supply structure. The power-supply structure comprises a power-supply input structure for receiving an external power-supply and a power-supply output structure for supplying power to the outside. The power-supply input structure and the power-supply output structure may be specified as power source interfaces. Optionally, a power source interface is respectively provided at the top and bottom of the housing of the humidifying device. A communication interface may also be provided at the top and bottom of the housing of the humidifying device. Further, the humidifying top cover 201 is provided with a combined power source and communication interface, that is, a lower combined power source and communication interface 217, and an upper combined power source and communication interface 216 is provided at the bottom of the humidifying device; of course, the power source interface and the communication interface may be two separate interfaces, and the positions can also be correspondingly arranged according to the positions of the interfaces of other devices which mate with the humidifying device. The power source interface, the combined power source and communication interface and the communication interface may employ the structure of the first terminal block or the second terminal block of the connector as described above.

The overall circuit is located in the centre of the water channel 241, coinciding with the position of the air duct, the lower combined power source and communication interface 217 is connected to a circuit connecting member 207 on the humidifying top cover 201, and the circuit connecting member 207 is then connected to the upper combined power source and communication interface 216 at the bottom of the humidifying device.

In order to fix in the air duct the lower combined power source and communication interface 217, the circuit connecting member 207 and the upper combined power source and communication interface 216 at the bottom of the humidifying device, the present invention is provided with a fixing frame 218 at the bottom of the humidifying device for fixedly connecting the components described above.

The humidifying device is provided with a connecting structure which is connected to the other devices described above, a slot 212 may be provided on the humidifying top cover 201 and a jaw 232 on the housing at the bottom of the humidifying device, so that the humidifying device is connected to the corresponding slot or jaw of the other device in a mating manner. Further, if the connection mode is snap-fit, magnet components may be attached to the humidifying device and other devices to make the mutual attraction between the devices be secure and facilitate mounting; of course, the magnet components may also be designed separately from the connection structure so that the humidifying device is connected to the other devices by means of attraction.

With the above embodiment, the following effects can be achieved: a simple structure, a good safety performance, no “white-powder” pollution, and easy to clean the device; and the principle of natural evaporation is adopted, such that the present invention is more green and healthy.

Reference is made to FIGS. 26-29, which are respectively first through fourth schematic views of a further humidifying device in some illustrative embodiments of the present invention.

In some optional embodiments, the humidifying device comprises an air duct penetrating axially through the humidifying device, a water tank 201 b for storing water, and a filter element 204 b disposed in the water tank, wherein the water tank 201 b surrounds the air duct.

In the pure humidifying device of the prior art, a water tank special for storing water is generally provided, and then the function of evaporating humidification is realized by means of a water channel (or a water reservoir); in this embodiment, only the water tank 201 b is provided, which water tank 201 b is configured as shown in FIG. 28, and may be regarded as a water channel, and the water tank 201 b is not only used for storing water, but also serves as a water channel. This design simplifies the structure of the prior art humidifying device and makes efficient use of the space, and the water tank 201 b can be designed to be larger without considering the space occupied by the water channel.

Furthermore, since the water tank 201 b surrounds the air duct, the water tank 201 b has a hollow structure, allowing the wind to pass through the water tank 201 b, so as to remove the water vapour around the air duct, i.e., the water vapour in the water tank 201 b, which can rapidly play the role of humidification.

In some optional embodiments, an inner wall 211 b of the water tank 201 surrounds the air duct, and the filter element 204 b is provided with a cavity penetrating through the upper and lower surfaces of the filter element. The filter element 204 b is fitted over the outer side of the inner wall 201 b of the water tank via the cavity. The filter element 204 b functions to improve the evaporation efficiency and purify the water in the water tank; therefore, the filter element 204 b is also designed to annularly extend along the air duct to match with the annular structure in the water tank 201 b so as to allow the air to pass through the water tank 201 b and also to pass through the filter element 204 b, thereby increasing the humidifying rate.

Further, in order to increase the area of the filter element 204 b in contact with the wind, in the process of designing the cavity structure of the filter element 204 b, the filter element 204 b is higher than the inner wall 211 b of the water tank 201 b. The inner wall 211 b of the water tank 201 b is lower than the outer wall 212 b, and the height of the filter element 204 b is the same as the height of the outer wall 212 b; therefore, the area of the filter element 204 b in contact with the wind throughout the humidification process comprises, in addition to the area of the upper surface, the area of a side wall of the filter element 204 b that is higher than the inner wall 211 b.

Further, the cavity of the filter element 204 b may be further modified such that the area of the bottom of the cavity is larger than the area of the top of the cavity, that is, the cavity of the filter element 204 b is shaped to have a larger upper opening and a smaller lower opening to increase the area of the side surface in contact with the wind, so that the wind is in better contact with the filter element 204 b and removes water vapour.

Optionally, the part of the filter element 204 b that is higher than the inner wall of the water tank may be provided with a bent portion which is bent inwardly, so as to achieve the following effects: first, increasing the area of the filter element 204 b in contact with the wind; second, increasing the area of the upper surface of the filter element 204 b; and third, making the wind in full contact with the filter element 204 b due to the reduced upper opening, so as to remove more water vapour.

Optionally, the filter element 204 b may be designed to be tapered, and the structure of the inner wall of the corresponding water tank 201 b may be configured accordingly.

In some illustrative embodiments, the water tank 201 b is separate from the housing of the humidifying device, and the humidifying housing is provided with a groove for having the water tank placed therein.

The inner humidifying housing 203 b is fixedly connected to the humidifying housing 204 b in such a manner as to be screw-connected, adhesive bonded or snap-fitted etc., the inner humidifying housing 203 b is provided with a groove the structure of which matches with the water tank 201 b, so that the water tank 201 b can be freely detached from the housing of the humidifying device for the convenience of the user. The upper portion of the water tank 201 b is then connected to the inner humidifying housing 203 b via an upper connecting bar 206 b, and the lower portions of the inner humidifying housing 203 b and the humidifying housing 202 b are fixedly connected to the humidifying chassis 209 b in such a manner as to be screw-connected, adhesive bonded or snap-fitted etc.

Furthermore, the bottom of the inner humidifying housing 203 b is spaced from the humidifying chassis 209 b by a certain distance, and a humidifying computer board (i.e. a humidifying PCB) for controlling the humidifying device is provided in the gap between the humidifying casing 202 b and the inner humidifying housing 203 b; the side of the inner humidifying housing 203 b that is surrounded by the humidifying housing 202 b may be fixed to the humidifying chassis 209 b via a bolt and the bottom edge of the other side of the inner humidifying housing 203 b may be connected to the humidification chassis 209 b via the lower connecting bar 207 b.

Optionally, the humidifying top cover 205 is provided with an air outlet, the upper surface of the filter element 204 in the water tank 201 can be observed from the air outlet, that is, it is understood that the upper surface of the filter element 204 is exposed to the air, so that the diameter of the air outlet is prevented from being designed too small, hindering the evaporation and escaping rates of the water vapour.

Optionally, the humidifying top cover 205 b is not disposed directly on the upper surface which is formed by the inner humidifying housing 203 b and the upper connecting bar 206 b, and the humidifying top cover 205 b is spaced from the upper surface at a distance in which a series of assemblies are provided, such as a power source interface and a communication interface. A lower power source interface 213 b and a lower communication interface 214 b are provided on the humidifying top cover 205 b; and similarly, a corresponding upper power source interface 211 b and upper communication interface 212 b are also provided on the humidifying chassis. Therefore, it is necessary to provide an insulating cover 210 b for insulating the water vapour between the humidifying top cover 205 b and the upper surface which is formed by the inner humidifying housing 203 b and the upper connecting bar 206 b, and the humidifying top cover 205 b is fixedly connected to the insulating cover 210 b. The lower power source interface 213 b, the lower communication interface 214 b, the upper power source interface 211 b and the upper communication interface 212 b may employ the structure of the first terminal block or the second terminal block of the connector as described above.

In some optional embodiments, the air duct runs through the centre of the humidifying device and is also located in the centre of the filter element 204 b.

Since the air duct needs to pass through the whole humidifying device, the whole humidifying device can be regarded as a ring-like structure (in cross section), the shapes of the inner and outer rings may be the same or different, and the inner or outer ring may be of a round, square or triangular structure; and the humidifying device is preferably concentrically ring-shaped, i.e. the structure as shown in FIGS. 17-20, and this design is more conducive to ventilation and evaporation of the water vapour.
